Optical chirality of the double “L” structure

Optical chirality of the double “L” structure The optical chirality of the double “L” structures is investigated by the finite element method in this paper. The simulated results show that the double “L” structure has distinct chiral effect for the distance less than 300 nm. For the double “L” structure with the angle of 90°, the peak wavelength of the extinction coefficient for the left circular polarized light is larger than it for the right circular polarized light. The CD spectra are almost at the same wavelength for the distance 175–300 nm, while its wavelength increases with the decrease of the distance from 175 to 100 nm. Although the chiral effect of the double “L” structure for the angle 75° is similar with the structure for the angle 90°, the chiral effect of the structure with the angle 105° is opposite with the structure for the angle 75° and 90°. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Optical and Quantum Electronics Springer Journals

Abstract

The optical chirality of the double “L” structures is investigated by the finite element method in this paper. The simulated results show that the double “L” structure has distinct chiral effect for the distance less than 300 nm. For the double “L” structure with the angle of 90°, the peak wavelength of the extinction coefficient for the left circular polarized light is larger than it for the right circular polarized light. The CD spectra are almost at the same wavelength for the distance 175–300 nm, while its wavelength increases with the decrease of the distance from 175 to 100 nm. Although the chiral effect of the double “L” structure for the angle 75° is similar with the structure for the angle 90°, the chiral effect of the structure with the angle 105° is opposite with the structure for the angle 75° and 90°.
